We loved our stay in Bangkok. We stayed at Effies for 2 nights and it was a good stay. The place is nicely decorated, the beds are Great and room is clean so is the rest of the place.
The Location is Great near tourist Locations, Just around the corner of an amazing streetfood place and near the waterferry where you can go Everywhere.
We would definitely recommend staying there even if you don't like hostels :)
